Part of fix for bug#52044 "FLUSH TABLES WITH READ LOCK and

FLUSH TABLES <list> WITH READ LOCK are incompatible" to be pushed as separate patch. Replaced thread state name "Waiting for table", which was used by threads waiting for a metadata lock or table flush, with a set of names which better reflect types of resources being waited for. Also replaced "Table lock" thread state name, which was used by threads waiting on thr_lock.c table level lock, with more elaborate "Waiting for table level lock", to make it more consistent with other thread state names. Updated test cases and their results according to these changes. Fixed sys_vars.query_cache_wlock_invalidate_func test to not to wait for timeout of wait_condition.inc script. mysql-test/r/query_cache.result: Added test coverage for query_cache_wlock_invalidate behavior for implicitly locked tables. mysql-test/suite/sys_vars/r/query_cache_wlock_invalidate_func.result: Fixed sys_vars.query_cache_wlock_invalidate_func test to not to wait for timeout of wait_condition.inc script. Reverted changes to test which introduced timeout and replaced waiting condition with a more appropriate one.

To implement this: - Adjusted MDL_wait::timed_wait() to take thread state name as parameter. - Introduced method of MDL_key class which allows to get thread state name to be used while waiting for resource corresponding to the key and changed code to use it. Added array translating namespaces to thread state names as part of this change. sql/mdl.h: To implement this: - Adjusted MDL_wait::timed_wait() to take thread state name as parameter. - Introduced method of MDL_key class which allows to get thread state name to be used while waiting for resource corresponding to the key and changed code to use it.
